Keeping Promises
Never permit yourself to threaten where you do not perform; children are quick to learn the value of your promises, and place very accurate estimates, in their own minds, as to what their parents will, or will not do under given circumstances. Absolute truthfulness can never be taught a child by precept, when by constant example he is taught that the word of his parents has little or no value in his own case, so far as threats and punishments, or even rewards, extend. If a punishment is the penalty for a broken law, see that it is inflicted; if a reward is promised, be sure that it is given.
Enjoin upon children strict justice in their dealings one with another, even in their games, never allowing the stronger to impose upon the weak, but teaching forbearance and tenderness in all their actions.
